  1. Undo: because rm -rf doesn’t have to be forever.

    This looks useful. Anyone tried it?

  3. …the undoing of the becoming undone or the becoming undone of the undoing?_

    sometimes i find it all just a bit of a stressful struggle 🫨🫩😕
    and other times life and i seem to float along together effortlessly

  4. experimenting with the ability to #undo moves (you can replay starting from any of the last 25 moves). also has unhinged 8x playback mode which is a hoot to watch. Try the matching settings and moving combinations.

  6. MVCC без VACUUM: что нам дал UNDO-лог, какую цену мы заплатили и зачем нам 5 механизмов сборки мусора

    Новая статья из цикла про нашу OLTP-СУБД на Rust. С самого начала мы выбрали MVCC на UNDO-логе вместо версионирования в heap, как в PostgreSQL. И годами повторяли свой же лозунг: «нет VACUUM, нет bloat». Оказалось, это правда ровно наполовину. Heap и правда не пухнет от истории версий. Но bloat никуда не делся: он переехал в индексы, в мёртвые слоты и в сам UNDO-лог. А сборка мусора из одного механизма незаметно превратилась в пять, и мы только сводим их к единому координатору. В статье разобрали без прикрас обе стороны. Что UNDO-модель дала: стабильный TID (UPDATE, который не трогает индексы), rollback пропорционально размеру транзакции, аналитику, не дорожающую от write-нагрузки, и AS OF как «машину времени» почти даром. И чем за это платим: главная эксплуатационная цена это долгоживущий снапшот, который молча останавливает очистку для всех. Вопрос к тем, кто эксплуатировал MVCC-базы под нагрузкой: что меньшее зло — блокировать GC ради долгих транзакций или отдавать «snapshot too old»? Любопытно ваше мнение в комментариях.

    A feature I didn’t know existed in VS Codium saved my day! I was working on a untracked Git file (the zensical.toml configuration file) and accidentally, the whole file was overwritten and ctrl+z didn’t work. I thought my config was lost for good!

    Luckily there’s a thing called “Local History”:

    3. Words like #DigitalAutonomy usually RELY ON OTHERS to do it *for themselves* and aside from a few changes I don't know you can help others to manage their own #life or #undo #addictions or do the #betterpractices stuff other than give them time to catch on to it and a few #tips or #handholding posts / principles etc.

    How could you speed up just general tips or convert them on to somethign else?

  15. Windows 2.x still thought it "knew better" than Mac when it came to keyboard shortcuts …

    Undo: Alt+Backspace
    Cut: Shift+Delete
    Copy: Ctrl+Insert
    Paste: Shift+Insert

    1990 would change that. Of course, the option-key shortcuts that Mac started in 1984 … ? Still waiting.

  17. I do not recommend this article: p367 begins "In short," & I had to laugh. But the idea is clear: we can stop corporations from spending on politicians or on voting policy, state by state.
    This defeats Citizens United (which 75% of USA wants taken down) w/o any court or Constitutional involvement.

  23. 🤩 Discovered a great article on jj!

    It explains how #jj was designed around concurrency to allow repo syncing. It treats #conflicts as first-class concepts to be resolved later and allows sparse #worktrees plus #undo on all repo operations.

  25. Technology that is helpful might be proactive – but then with a robust Undo function – or it might wait in the background untill called. It depends on the context.

    Technology that is helpful doesn't harass.

  26. What a frustrating thing using a computer must be for those who don't know that Ctrl-Z can Undo almost any mistake they make on a computer.

    If you're one of those people, I have good news for you! If you accidentally deleted some text, it magically reappears when you hold down the Ctrl button on your keyboard, and press the Z button while you're still holding it. This works for a whole range of things.

    Undo is an everyday superpower we all have access to.

  28. CW: Artist's nightmare when considering to re-do something and potentially ruin it or perfect it...

    You know when you make something almost perfect, and you consider making it "better" ?
    By doing "better" some part might get worse or change the style like editing a picture or editing the video and loosing some other essence you had before (but don't realise) and at the end when compared it has a bit of really good parts but more obvious as another layer or redo?...

    An #artists nightmare !

    That's why we need others to say:

    💬 " leave it - it's great - really - and you might fuck it up royal " or

    💬 " just make another one, and save this one the risk "

  29. Episode seventy-seven is up now! Today's song is Voice in Headphones by Mount Eerie with Julie Doiron & Frederick Squire.

    I discuss the way this song weaves in the lyrics of the song that inspired it, and how much this song about how much a song means to someone has come to mean to me.

    I discuss the layered and complex production of the song, and its relatively straightforward lyrics.

  31. Buggeration. I've managed to subscribe my tiny ActivityPub server to a Lemmy community and I'm now being inundated with messages about who liked what, which communities have been blocked, downvotes etc.

    When I send an #Undo message in #ActivityPub, does it need to contain the same ID as the follow request?

  33. more #OldGeezer thoughts on this (oh no). it seems like #ComputerGames nowadays are built with this idea that you can simply #UNDO all your mistakes. "missed it? don't worry, you can just go back!" and this is seen as #GOOD but is it really? i don't know why this is so offensive -- maybe it's not? -- but you can't just GO BACK when you f%&k up in life; you live and learn (Sonic Adventure 2 reference). of course, games don't need to be like #RealLife BUT! there is no but, it's just perspective.

  34. As part of tackling the undo system I decided to spend a little time building a debug view that shows the undo buffer on-screen.

    Now to actually ... do something with that buffer.
